The story goes that in 1835 Mr James Newlove lowered his young son
Joshua into a hole in the ground that had appeared during the digging of
a duck pond. Joshua emerged describing tunnels covered with shells. He
had discovered the Shell Grotto, its walls decorated with strange
symbols mosaiced in millions of shells.

Is it an ancient pagan temple? A meeting place for some secret cult?
Nobody can explain who built this amazing place, or why, but since its
accidental discovery visitors from all over the world have been
intrigued by the beautiful mosaic and the unsolved mystery.
